2024-07-09wifi: mt76: mt762x: extend mt76_connac_mcu_sta_basic_tlv for per-link STASean Wang1-1/+4
Extend mt76_connac_mcu_sta_basic_tlv with the per-link STA configuration. The patch we created is a prerequisite to enable the MLO function in the driver. It is purely a refactoring patch so the functionality should remain unchanged.

2024-06-20wifi: mt76: un-embedd netdev from mt76_devBreno Leitao1-1/+1
Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_devices from struct mt76_dev by converting them into pointers, and allocating them dynamically. Use the leverage alloc_netdev_dummy() to allocate the net_device object at mt76_dma_init(). The free of the device occurs at mt76_dma_cleanup().

2024-05-02wifi: mt76: mt7996: let upper layer handle MGMT frame protectionMichael-CY Lee1-4/+5
The firmware support for management frame protection has limitations: - do not support cipher BIP-GMAC-128 and BIP-GMAC-256 - support cipher BIP-CMAC-128 and BIP-CMAC-256, except action frame with action type 'not robust'.

There are still surprisingly many non-chanctx drivers, but in mac80211 that code is a bit awkward. Simplify this by having those drivers assign 'emulated' ops, so that the mac80211 code can be more unified between non-chanctx/chanctx drivers. This cuts the number of places caring about it by about 15, which are scattered across - now they're fewer and no longer in the channel context handling.
